[Solved] Fedora 23 + Gnome + Hexchat, window opening issue

Hi, I just started using Vivaldi today and I like - A LOT - but one annoying thing. I set the browser to be system default, but when I click a link in my IRC client the tab opens (somewhere) but in some background state so you can't see it (but you can hear it if it's a YouTube video or something, and you can see the process in the system monitor). This isn't a system wide issue - LibreOffice, for example, opens links just fine, as does the system default PDF reader. It's just Hexchat that has this issue it seems (and yes, I did restart it and Gnome too). It doesn't have this problem with Google Chrome or Firefox - when they are the system default browser they behave as expected - link clicks work fine, open a new tab at the end of the existing tabs. It's just Vivaldi that seems to cause this weird "background tab" kind of behaviour, where you have to hunt down the process and kill it to clear the invisible tab.

Let me know if you need more information, logs, etc.

For some reason this appears to have cured itself. I'm not sure what I did, it might be because I juggled tabs around in Vivaldi, it might be something else, but the problem has gone away. Weird! Information is here if anyone cares to try and repeat it. I will re-post if I can figure out a way to reliably repeat the behaviour. But for now, nothing to see here!
